This section describes advanced routines for explicitly manipulating
Field components.
Since these routines expect the input to be a copy of the Object, they
operate directly on the input without making another copy.
For additional information on components, see
<A HREF="usrgu024.htm#HDRDATMOD">Chapter 3. "Understanding the Data Model"</A>
in <I>IBM Visualization Data Explorer User&#39;s Guide</I>.
